MOVING DISPLAY APPARATUS FOR JEWELRY.

Application filed September To all whom it may concern.

Be it known that I, Crmnnns E. CHAPMAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful improvements in a Moving Display ;pparatus for Jewelry, of which the following .ification.

This invention relates generally to improvements in apparatus foresnibiting or displaying mechandise. but has particular relation to adevice to be used for movably displaying in the show cases or showwindows of jewelry stores, that type of pieces of jewelry which carry orhave mounted thereon brilliant settings, gems, precious stones, orimitations thereof. for instance. linger rings, ear-rings, brooches,scarf-pins, h fr ornaments, and the like, and it consists in certainpeculiarities of the construction, novel arrangement and combination ofthe various parts thereof as will be hereinafter more fully set forthand specifically claimed.

The principal object of the invention is to provide an apparatus of theabove mentioned general character, whereby one or more platforms ortables thereof, on which PJiECQS Of jewelry are mounted. will beautomatically tilted towards and from the ob server or prospectivepurchaser, to the end, that the settings of the pieces of jewelry willbe subjected to the rays of light at varying angles. thereby causing thestones or settings to scintillate. flash or sparkle and to otherwisebetter display their beauty or attractiveness.

Another object is to provide a display apparatus of such constructionand arrangement of its parts, that a plurality of trays, each having aplurality of tiltable platforms on which pieces of jewelry may bemounted, can be operatively disposed on the main or supporting frame ofthe apparatus in such a way that they can be handled as a unit, and sothat their respective sets of platforms will be tilted successively inpairs, by the same motive power.

A further object is to so make the apparatus that itsoperative-mechanism will be self-contained and invisible to customers,yet simple and inexpensive in construction, strong, durable andefficient in operation.

Other objects and advantages of the invention will be disclosed in thefollowing description and explanation.

In the accompanying drawings, which Specification of Letters PatentPatented An". 15, 1922.

Serial No. 501.370.

Corresponding numerals of reference refer to like parts throughout thedifferent views of the drawings.

Referring now more particularly to Figs. 1 to 3 inclusive of thedrawings, the reference numeral 10 designates the main or supportingframe of the apparatus, which frame may be made of any suitable size,form and material but preferably of wood or metal and of an elongatedrectangular shape as shown. The end pieces 11 of this frame are unitednear their upper edges and about midway between the sides 12 of theframe by means of a longitudinally and horizontally disposed bar 13,which bar may have its ends fastened to the inner surfaces of the endpieces 11 by any suitable and secure means. Located on top of the bar 13and eX.--

tended longitudinally thereon from one of the end pieces 11 of the mainframe to the other end piece thereof, is a cleat 14: on the uppersurface of which rests the stationary floor or platform 15 of the frame,the edges of which lie and are suitably secured in vertically disposedrecesses orrabbets 16 located in the upper edges of the supporting frameas will be clearly understood by refer ence to Fig. 3 of the drawings.This floor or platform may be covered with felt, plush .or any othersuitable covering, not shown.

The end pieces 11 of the main frame are also united about midway betweenthe side pieces 12 of said frame by means of a longitudi nally extendedbar 17 on theupper surface of which is mounted the inner end of a floor18 the outer end of which is mounted on a horizontally andlongitudinally disposed bar 19secured on the inner surface of one of theside pieces 12 of the main frame at the lower edge thereof. The floor 18has mounted on its upper surface near its inner end an'upright bracket20 which carries an idle roller or pulley 21 for the purpose to bepresently middle portions onthe upper surface of the longitudinallydisposed bar 13 and are suit.

ably secured at their ends to the inner sur faces of the side pieces 12of the main frame.

These bars 22 assist in supporting the floor 15 of the main frame andeach of them is provided with apair of vertical openings 22 has fittedtherein a tubular extension 23 on the lower surface of a grease cup orreceptacle 24, which cups and extensions are preferably made of metal.The extension 23 of each cup is extended through a suitable opening inthe floor 15, which opening reg isters with one of the openings in thetransverse bars 22. By reference to Fig. 2 of the drawings, it will beseen that the cups 2-1 are annular in shape and may be imbedded inthefloor 15 as shown so as to surround theopenings in which theextensions 23 are located so as to more securely hold said cups 1nposition.

Longitudinally journaled in the end pieces 11 of the main frame at oneside of the bar 13 and in parallelism therewith, is a shaft25, on whichis mounted to turn therewith a pulley 26, which is by preference of theperipherally grooved type. Fixed 011 the shaft 25 directlybelow each ofthe transverse bars 22is an eccentric disk orcam.

Referring now to Figs. 2 and 3 of the drawingsqit will be understoodthat theeccentric disk designated by the numeral 27, is located underthe bar 22 adjacent the left hand end of the main frame of theapparatus, and that the disk28 is located under the bar 22 at the"middle of the main frame, while the disk oreccentric 29 is locatedunder the transverse bar 22 near the right hand end of the main frame.It will also be seen in. Fig. 3 that these eccentrics or disks are somounted on the shaft 25 as to present theirgreatest eccentricity in therotation of the shaft 25 at different intervals, thereby causing; thelevers with which they contact to be elevated and lowered successfully.

Mounted on the floor 18 of the main frame near oneof the sides of saidframe is an electric jmotor 30 of the ordinary or any preferredconstruction, which may be connected to a source of electric supply inan ordinary or well known manner. Mounted on the floor 18 near one endof the motor 30 is a gear casing 31 in which is transversely journaled ashaft 32 which carries on one of its ends a grooved pulley 33, andwithin the casing 31 a pinion 34C. The grooved pulley 33 is geared tothe shaft 35 of the motor by means of a belt 36 which passes over thepulley 33 and a pulley 37 on the end of the motor shaft 35 adjacent thegear casing. The pinion 3 1 meshes with a near 38 mounted on a shaft 39transversel journaled in the casing 31, which shaft has mounted thereona pinion 10 in mesh with a gear -11'mounted on a shaft 42 transverselyjournaled in the casing 31 as is clearly shown in Fig. 1 ofthe'drawings. This last named shaft has mounted thereon outwardly of thegear casing 31 and on the opposite side thereof from the motor, agrooved pulley 43 over which is extended a belt 14, which belt alsoextends around the pulley 23of the driven shaft of the apparatus. Byreference to Figs. 2 and 3 of the drawings, it will be seen thatthe belt4 1 is adapted to rest on the. idle pulley 21 so that undue slachness ofsaid belt may betaken up or compensated for.

Secured to the lower surface of the bar 13 and depending therefrom undereach of the transverse bars 22 is a bracket 45, (see Fig. 3) to thelower portion of each of which ispivotally secured at about its middle,a lever 16 each of which levers is located directly under one of thetransverse bars 22 and is adapted to be moved in a vertical planethereunder, by means of the eccentrics 27, 28, and 29, on which thelevers 16 rest near one of their ends. Each of the levers 4:6 isprovided at its end adjacent its co-acting eccentric with a weight 47which are employed to constantly hold. said. levers in contact withtheir respective eccentrics.

Pivotally connected at one of its ends to each of the levers 16 near theweighted end thereof is a link 43, the other end of each of whichispivotally connected to the lower end of a lifting rod or plunger 19,which plungers are extended through the tubular extensions 23 of thegrease cups 24 located on that portion of the floor 15 of the main frameabove the weighted ends of said levers.

Pivotally connected at one of its ends to the opposite end of each ofthe levers 46 is another link 48 each of which is pivotally connected atits other end to a lifting rod or plunger 49 extended through thetubular extensions 23 of the grease cups 24: located on that side of thebar 13 opposite the first above mentioned grease cups. Each of thelifting rods 49 has its upper end rounded as at 50, and is provided witha channel or bore 51 extended from its upper end downwardly a suitabledistance and then laterally as at 52, see Fig. 5, so as to provide meansfor the passage of a lubricant to the tubular extensions 25 in which thelifting rods oper ate.

Each of the levers 16 is provided above the eccentric on which it restswith a grease cup 53 having an outlet through its lever for depositinglubricant on its supporting eccentric.

Mounted on the floor 15 of the main or supporting frame are a plurality,usually 6, of rectangularly shaped frame-like trays which are designatedby the numerals 54, 55, 56, 57, 58, and 59. These trays, as is clearlyshown in Figs. 1 and 2 of the drawings, are located in pairstransversely of the main frame, that is to say, the trays 5 1, and 55,constitute one pair of trays, 56 and 57, another pair, and the trays 58and 59 a third pair. Each of these trays has a plurality of platforms 6Opivotally'mounted at one of their longitudinal edges on spaced rods 61secured in parallelism with one another on the end pieces of the tray.Each of these platforms is provided at one of its ends with an upturnedlug 62, which lugs on the set of platforms located in one of the trays,are loosely connected together by means of a bar 63 pivoted to saidlugs. Each of these platforms 60 is preferably pivotally secured on oneof the supporting rods 61 therefor by means of a flange 64 which is bentupwardly and then towards the upper surface of the platform so as toloosely receive its supporting rod 61. These flanges 64: not only serveto pivotally secure the platforms 60 on their respective supporting rods61, but also serve the purpose of engaging and holding the lowerportions of cards 65 on the upper portions of which a piece of jewelry66 may be mounted in the ordinary way. These cards may be located on theupper surface of the platforms 60 with their lower edges interposedbetween the fianges 64 and the body of the platforms, as will be readilyunderstood by reference to Fig. 6 of the drawings.

By connecting each set of the platforms 60, that is to say, theplatforms located in each of the trays at one of their ends by means ofthe bars 63 and lugs 62, it is apparent that any movement of any oneplatform of a set will cause the other platforms of said set to move ina corresponding direction. As these platforms are connected in sets bythe bars 63 which are located above the supporting rods 61 for saidplatforms, it is manifest that the downward movement of said platformswill be restricted to horizontal positions as shown in the left handcorner of Fig. 1 and the left hand portion of F 3 of the drawings, whiletheir movements in an upward direction will be limited to that of theupward strokes or movements of the lifting rods 1-9 which impingeagainst the lower surface of the intermediate platform of each set.

From the foregoing, and by reference to the drawings, it will be readilyunderstoodand clearly seen, assuming that the parts are in the positionsshown in Figs. 1 to 3 in clusive of the drawings, and that it is desiredto start the apparatus for movable operation, it is only necessary toturn on the electric current to the motor 30, which will thereby be setin operation, thuscausing the shaft 25, through the instrumentality ofthe gearing connecting it and the motor to be driven, when, by reason ofthe position of the eccentrics 2?, 28 and 29, on said shaft, the levers16 will be tilted in such a way as to cause the sets of platforms in thetransversely disposed pairs of trays to be alternately raised andlowered.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. In a display apparatus of the classdescribed, the combination with a supporting frame, of a lever mountedtherein for oscillation in a vertical plane, a plurality of displayplatforms horizontally and tiltably mounted side by side on said framecrosswise of and above said lever for unitary movement, means carried bythe lever and separably co-acting with one of said plat-- forms to tiltthe same upwardly and means to oscillate the lever.
